FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 416,968, dated December 10, 1889..

Application filed June 19, 1889. Serial No. 314,873. (No model.)

1'0 all whom if 77mg concern..-

Be it known that I, MARCUS A. SWING, of lVashington, in the county of Daviess and Stat-e of Indiana, have invented a new and useful Improvement in Feed-Regulators, of which the following is a specilication.

My invention consists in a new and improved feed device or regulator for rollermills, which will be hereinafter fully described and claimed. Referring to the accompanying drawings, Figure l is a perspective view. Fig. 2 is an end view with the end piece l partly broken away, and Fig. 3 is a detail perspective view hereinafter referred to.

The same numerals of reference indicate corresponding parts in all the figures.

Referring to the several parts by their numerals, 1 1 indicate the end pieces of my device, which are preferably formed of metal one-eighth of an inch thick. Between these end pieces are secured by bolts or screws the stationaryback board 2,brace 3, and top bare.

My invention is secured to the frame of a roller-mill above its revolving rolls, between which Athe grain is crushed, by a common wood-screw 5 at each end, as shown in Fig.

In a bearing 6 at the lower end of one end piece 1 is journaled loosely one end of a shaft 7, on the other end of which is secured a rubber wheel 8, the outer side of this wheel being ush with the outer side of the end piece 1. rlhis end of the shaft 7 is mounted in a' bearing in a wooden block 9, which is secured to a metal lever-arm 10. This lever-arm s pivoted at its inner end on the left-hand pivot-screw 11, and is formed with a transverse slot 12, through which a screw 13 passes.

The rubber wheel S is raised or lowered by turning a set-screw 14 to drop and hold the said wheel in contact with one of the revolving rolls of the mills and secured in this position by tightening the screw 13, the setscrew holding the wheel firmly at the point to which it is adj usted.

The fall-board 15 is pivoted at its upper end by end pivots 16 just below the top bar 4, and is held in at its lower end by springarms 17, secured at their upper ends on the top bar 4, with their lower free ends pressing the lower end of the pivoted board 15 in toward the hack board 2. These spring-arms 17 can be adjusted in and'out by means of set-screws 18, which work in the top bar 4., as shown.

The shaft 7 is formed near each end with lthe opposite flat recesses 19 19 and 2O 20, the

loosely on the pivot-screws 11, the outer free ends of the wires extending under and in contact with the ends of the revolving shaft 7, where they are formed with the flat recesses 19 20. The inner ends of the treadlewires iit under the lower edge of the feedbar 21, preferably in eyes 23. The feed-bar 21 is the same length as the pivoted board 15, and is held movably in the position shown between the lower edge of the pivoted board 15 and the back board 2 by a curved springwire 24, the lower ends of which pass through and are secured to the feed-bar. The springwire 2t is secured to the back board 2 at its bent upper end by a screw 25, the upper central part 2G of the wire through which the screw passes being bent, so that by tightening this screw 25 the feed will be lessened, as when the screw is loose the entire supportingwire can slide up and down, while by tightening the screw the wire is held stationary at that point and can only be compressed bythe moving feed-bar, thus lessening the feed.

In operation as the shaft 7 is revolved the flat recesses 19 and 20, as they come in contact with the ends of the wire treadles, will oscillate up and down, and at the same time impart a rocking motion to the feed-bar 2l, and the gra-in will thus be fed in a steady, even, and continuous stream from the hopper to the revolving rolls of the mill.

27 27 indicate set-screws, which can be raised or lowered on the wire treadles to regu'- late the stroke imparted to the treadles by the revolving shaft 7.

It will beseen that my invention does away IOO with all the small pulleys and belt-ing heretofore used on the outside of the roller frame or casing Where the feed-regulator was driven from the roll shaft or shafts of the mill, as in my invention I drive the feed-regulator directly from and off the mill-roll on the inside of the roll frame or casing.

Rubber Wheels 8 of different sizes will be used to suit the speed of different mill-rolls.

Having` thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, with a suitable hopper, of the'revolving shaft having' the rubber Wheel at its end and formed with the flat recesses, the centrally-pivoted treadle-Wiies', the board 15, pivoted at its upper end, and the feed-bar, substantially as set forth.

2. The combination, With a suitable hopper, ot' the revolving shaft loosely fitting in a bearing at one end, having the rubbeiw'h'eel at its other end, and forin'e'd With the nat .recesses, the bearing-block 9, the pivoted leverarm formed With the transverse'slot and the set-screws 13` and 1l, the centrally-pivoted treadle-Wires, the board 15, pivoted at its upper end,and the feed-bar,substantially as set forth.

3. The combination, with a suitable hop'- per, of the revolving,` shaft having" the rubber wheel at its end'fand forined `With the iiat recesses, the centrally-pivoted treadle-Wires, the set-screws 27 27, the board 15, pivoted at its upper end, and the feed-bar, substantially as set forth.

4. The colnbination,with the hopper, of the revolving shaft having the rubber Wheel at its end and formed with the flat recesses, the centrally-pivoted treadle-Wires, the feed-bar, the board 15, pivoted at its upper end, the curved spring-Wire 21, and the screw 25,sub stantially as set forth.

5. The combination, with the end pieces, the back board, and the t-op bar 4, .of the board 15, pivoted atits upper end, the curved spring-arms 17, the feed-bar, the spring-Wire 24, the centrally-pivoted treadle-Wires, and the revolving shaft having` the rubber Wheel atvone end and formed with the hat recesses,4

substantially as set forth.

6. The combination, with the end pieces, the back board, and the top bar 4, of the board 15, pivoted at its upper end,t`ne curved sprin, ,r-arrnsv 17, the set-screws 18, the feedbar, the spring-Wire 24 and its screw 25, the ceiitrally-pivoted treadle-Wires and their sets'crews 27, the revolving shaft having the rubber Wheel at one end and formed with the nat recesses, the bearing-block 9, the pivoted slotted lever-arni, and the set-screws 13 and 14, substantially as set forth.
